Photoalignment possesses obvious advantages in comparison with the usually “rubbing” treatment of the substrates of liquid crystal display (LCD) cells. The liquid crystal photoalignment is nano-technology, as the thickness of the alignment layer is about 2-15 nm. The application of the photo-alignment and photo-patterning nano technology for the new generation of photonic and display devices wi...

(2013). X-ray scattering of a nematic liquid crystal nano-dispersion with negative dielectric anisotropy. A nematic liquid crystal (LC) mixture was doped with harvested ferroelectric BaTiO 3 nanoparticles and investigated with wide-and small-angle x-ray scattering upon heating from the nematic to the isotropic phase. At moderate temperatures, colloidal crystallites were observed. LC test cells ...

We developed a computational method to predict the retention times of peptides in HPLC using artificial neural networks (ANN). We performed stepwise multiple linear regressions and selected for ANN input amino acids that significantly affected the LC retention time. Unlike conventional linear models, the trained ANN accurately predicted the retention time of peptides containing up to 50 amino a...

background and objectives: thermal processing is an effective method in preventing microbial spoilage but high heat transfer in a long time process that leads to quality loss and increased energy consumption. also it is important to consider sensitive nature of food products during the thermal processing. due to the nano-fluids' unique thermo–physical properties compared with the conventio...

BACKGROUND Biomarkers are required for pre-symptomatic diagnosis, treatment, and monitoring of neurodegenerative diseases such as Alzheimer's disease. Cerebrospinal fluid (CSF) is a favored source because its proteome reflects the composition of the brain. Ideal biomarkers have low technical and inter-individual variability (subject variance) among control subjects to minimize overlaps between ...

Quantitative structure–retention relationships (QSRR) have been derived for prediction of RP-HPLC retention of peptides obtained by online digestion of myoglobin. To characterize the structure of a peptide quantitatively, and then to predict its retention time under gradient HPLC conditions, the structural descriptors used were: the logarithm of the sum of retention times of the amino acids of ...

the microbial fuel cells (mfcs) are a kind of systems through which the anaerobic bacteriaalong with the oxidation of simple or complicated organic matter in the wastewater can generate the electricpower. this is a modern approach used in generation of the clean and renewable energy. in this research, two pilot laboratories of double-chamber microbial fuel cells were made. one of them contained...

The scanning electron microscope (SEM) has been successfully used as an analysis tool for nano-scale materials in nuclear and special materials applications for many years. Recently, the large chamber (LC) SEM at Y12 has demonstrated its power in surface analysis and inspections of large specimens at the nano-scale without destruction of the specimen. This paper summarizes the research efforts ...

This study investigated ageing-resistant properties of carboxyl-terminated polyester (polyethylene glycol terephthalate) composites modified with nanoscale titanium dioxide particles (nano-TiO2). The nano-TiO2 was pretreated by a dry coating method, with aluminate coupling agent as a functional grafting additive. The agglomeration resistance was evaluated, which exhibited significant improvemen...
